2 A Behavioral Economics Approach to the Poor Scarcity: Why Having Too Little Means So Much – By Sendhil Mullainathan and Eldar Shafir, Times Books, 2013

3 Two Dominant Views of Behavior Under Poverty The poor behave rationally – They are poor because they have few productive resources or bad luck, but their choices are rational The poor behave pathologically – They are impatient, don’t plan, and are confused – The poor are different – They are poor because they make bad choices

4 Behavioral Economics and the Poor Behavioral economics says: – Yes, people become poor because they have few productive resources or bad luck – But scarcity then reduces their cognitive bandwidth—that is, their attention, cognitive ability, and self-control—and thereby leads them into bad choices – This makes them fall deeper into poverty

5 The WWII Starvation Experiments After WWII, the victorious Allies found lots of people who had been starving for a long time What was the safest way to feed them? – Let them eat as much as they wanted from the get-go? – Or, increase their food intake gradually? An experiment was conducted in which volunteers were starved

6 The WWII Starvation Experiments The men became impatient waiting in line if the service was slow. They were possessive about their food. Some hunched over their trays using their arms to protect their meal. … Dislikes for certain foods, such as rutabagas, disappeared. – Hunger by Sharman Apt Russell None of this was surprising

7 The WWII Starvation Experiments But some observed changes were unexpected Obsessions developed around cookbooks and menus from local restaurants. Some men could spend hours comparing the prices of fruits and vegetables from one newspaper to the next. Some planned now to go into agriculture. They dreamed of new careers as restaurant owners. …

8 The WWII Starvation Experiments … They lost their will for academic problems and became far more interested in cookbooks. … When they went to the movies, only the scenes with food held their interest. – Hunger by Sharman Apt Russell Scarcity (in this case, of food) captured the attention of people and made it impossible for them to think about anything else

9 Scarcity Captures Attention Scarcity captures our attention and makes it difficult for us to think about anything other than the source of the scarcity And this capture of our attention is involuntary We have no choice in the matter

10 Poverty and Its Puzzles The poor tend to care less for their health – Use less preventive healthcare – Comply less with treatment regimes (Case et al AER 2004) The poor are less attentive parents – Better off parents read more to their kids, engage them in more conversations, take them to cultural/educational events more often, regulate the amount of TV that their kids watch more… The poor pass up on productive investment opportunities… – …despite having resources and knowledge to do so (Duflo et al 2010) Poverty is correlated with “bad” behavior. WHY ??

11 Possible Explanations Good things cost money – Example: medicines cost money Factors associated with poverty – Poor are less knowledgeable The poor are just different people – Care less about the future, less intelligent

12 Possible Explanations Good things cost money – Ex: drugs cost money Costs do not matter for many behaviors Factors associated with poverty – Poor are less knowledgeable Doesn’t quite explain many behaviors of the poor The poor are different people – Care less about the future, less intelligent

13 Poor are Worse Decision Makers One explanation for poverty: – (Bad) Decision-Making  Poverty Alternative Explanation: – Poverty  (Bad) Decision-Making

14 There’s Something About Scarcity The poor must manage sporadic income, juggle expenses, and make difficult financial tradeoffs. Mental bandwidth is limited Concerns about (financial) scarcity are taxing… – They capture our attention (mental bandwidth) and trigger intrusive thoughts … – … leaving less for other important, but less urgent tasks Why should the mind be structured like this? – Capture is involuntary

15 Scarcity Focuses Our Minds In one study, the participants came to the lab around lunchtime, not having eaten for three to four hours Half of them were fed lunch (full), the other half wasn’t (hungry) They were all then given word recognition tests

16 Scarcity Focuses Our Minds The full and the hungry did equally well for neutral (not food-related) words The hungry did much better on food-related words Scarcity captures our minds and focuses on the scarcity This capture is involuntary (automatic)

17 Scarcity Focuses Our Minds Thirst made experiment participants focus on thirst-related words, such as water When asked to estimate the sizes of various coins, poorer children consistently gave bigger estimates

18 Focus Dividend Scarcity captures our minds and makes us focus on the scarcity This helps us make better choices regarding the source of the scarcity Scarcity makes us more efficient users of the thing that is scarce – This is the focus dividend, the good side of the psychological effects of scarcity

19 Tunneling Unfortunately, we cannot control the effect of scarcity on our minds We cannot turn the focus dividend on or off as we wish We may stay focused on the scarcity when we desperately need to focus on something else – This is the tunneling tax of scarcity – We look at the world as though through a tunnel

20 The Bandwidth Tax Scarcity reduces our cognitive bandwidth – Our IQ scores go down – Our self-control decreases This is the bandwidth tax

21 Evidence on the Bandwidth Tax Picture identification experiment Push a button when you see a red dot on the computer screen Sometimes, just before the dot appeared, another picture would flash on the screen Do people see the red dot and press the button?

22 Evidence on the Bandwidth Tax For non-dieters, the picture had no effect on whether people saw the dot Dieters were less likely to see the dot if they had just seen a picture of food For people facing scarcity, the source of the scarcity captures their attention and makes it difficult for them to focus on other things

23 More on the Focus Dividend Work meetings become more productive towards the end Fixed deadlines work better than flexible ones Coupons are less likely to be used if they have no expiration dates Sales people work hardest in the last weeks of the sales cycle

24 More on Tunneling Between 1984 and 2000, vehicle collisions accounted for between 20 and 25 percent of firefighter deaths In 79 percent of these cases, the firefighters were not wearing seat belts Firefighters know very well the need for seat belts But in the rush to a fire scene, they tunnel

25 Tunneling leads to bad choices Tunneling makes us ignore tasks that are crucial but do not appear urgent

26 Tunneling leads to bad choices A family suffers a misfortune and falls into poverty. It needs to reduce its regular cash outflow. It switches its car insurance to a plan with a higher deductible and lower premium. It focuses on reducing premiums and tunnels out the bigger future expenses it would face in case of an auto accident In general, the poor ignore insurance of various kinds, and end up tunneling

27 The Bandwidth Tax The experimental subjects were given a grid of letters and asked to find a particular word (such as “street”) Then another And another, etc.

28 Search for a neutral word

29 The Bandwidth Tax A second group was given a list in which – the odd-numbered words were the same as before, but – the even-numbered words were food-related

30 Search for a food-related word

31 The Bandwidth Tax Dieters took 30 percent longer (than non- dieters) to find CLOUD after they had just searched for DONUT DONUT captured the attention of the dieters and would not let go They were still thinking about DONUT when they were supposed to be searching for CLOUD

32 EXPERIMENTAL STUDY: Trigger thoughts about Financial concerns by presenting hypothetical scenarios to mall shoppers … Give them IQ tests as they’re thinking about how they would deal with the scenario FIELD STUDY: Farmers financially stretched before harvest, richer after they’re paid. Compare IQ test performance of the same farmer before harvest versus after harvest (when he is richer) Evidence for the Hypothesis

33 Cognitive Tests Respondents shown a string of (identical) numbers; Task is to count the number of digits, not the number itself Raven’s TestsNumber Stroop Tests

34 Study in a NJ Mall Scenario: Your car breaks down and requires $300 to be fixed. You can pay in full, take a loan, or take a chance and forego the service at the moment... How would you go about making this decision? Financially, would it be an easy or a difficult decision for you to make? This was followed by Raven’s Matrices tests for IQ The rich and the poor did equally well

35 Study in a NJ Mall The experiment was then repeated, but the repair cost was given as $3,000 The rich subjects now did as well as before The poor did significantly worse Preoccupied with scarcity, their IQ went down!!

36 Findings Financial Stress results in a drop of IQ points…which is the equivalent of IQ lost – From loss of a full night’s sleep – From becoming a normal drinker to an alcoholic – Going from 45 to 60 years of age

37 Conclusions and Policy Implications Poverty is not just about material resources, but also about lower mental resources Policies should be created in a way to reduce the cognitive demand in the poor – Set up the right default in retirement plans, health insurance, bank accounts – Simplify forms, application procedures – Set up commitment devices and timely reminders

38 Loss of Executive Control We have discussed Walter Mischel’s 1960s marshmallow experiment That experiment showed how important self- control is as a determinant of success in life Unfortunately, scarcity reduces self-control

39 Loss of Executive Control Self-control relies heavily on executive control Executive control is essential when we need to – Direct attention – Initiate an action – Inhibit an intuitive response – Resist an impulse These abilities are tested by psychologists using a simple test

40 Loss of Executive Control Another experiment in the NJ Mall – You got a problem with that? As before, the subjects were presented with hypothetical financial problems, either easy ($300 car trouble) or hard ($3,000 car trouble) Then they were shown in quick succession and at random either a heart  or a flower  The task was to click the same side as the heart and the opposite side of the flower

41 Cognitive Control Task

42 Loss of Executive Control The natural instinct is to click on the flower when it appears But this urge has to be resisted because the subjects are required on the opposite side when a flower appears This requires executive control

43 Loss of Executive Control After the easy scenario, both the rich and the poor did equally well After the hard scenario, a dramatic difference appeared: – The rich did just as well as they did after the easy scenario – The poor did significantly worse. They clicked more impulsively on the flower rather than on the opposite side

44 Scarcity Taxes our Bandwidth The New Jersey Mall experiments show that scarcity appears to make us – Dumber, and – More impulsive Keep in mind that after the easy financial scenario the rich and the poor did equally well in both the IQ tests and in the executive control tests

45 Sugarcane Farmers in India Each sugarcane farmer harvests one crop per year The farmer tends to be really poor immediately before the harvest and a lot more financially comfortable after the harvest The farmers were given the Raven’s matrices test for IQ and the heart-flower test or the Stroop test for executive control, some before harvest and some after the harvest

46 Sugarcane Farmers in India On both intelligence and self-control, farmers did much worse before the harvest than after Here the difference is not because the people are different Only their circumstances are different

47 Executive Control Psychologists have found that self-control is finite The poor spend most of their lives being tempted by things that cannot afford This exhausts their self-control As a result, when a really big temptation comes along, they may not have any self- control left to resist it The rich are less likely to face this problem

48 Summary The poor exhibited diminished cognitive abilities when financial problems were challenging, but were comparable to the rich when problems were benign Field and lab evidence suggests that financial scarcity presents challenges that consume cognitive resources, leaving less for other tasks, hence impeding other basic cognitive functions

49 Conclusions and Policy Implications A new explanation for why the poor appear less capable: The state of poverty hurts mental capacity Policies should be created in a way to reduce the cognitive demand in the poor – Set up the right default in retirement plans, health insurance, bank accounts – Simplify forms, application procedures – Set up commitment devices – Reminders

50 More Than Poverty Scarcity more broadly Studies on the lonely Studies on dieters Experimentally constructed scarcity
